In Extended Reality (XR), the consumer is immersed in a visual environment mainly represented using a combination of meshes and textures [1]} or sometimes a full plenoptic representation [2]}.
For improved realism, the amount of visual data necessary to generate realism in the render engine has exploded during the last years, making techniques such as pre-caching a necessity.
For the render engine to pre-cache visual information, it should be able to predict where the participant will be positioned or looking at [3]} in the near future.
Since people have free will, it is impossible and unnecessary for this application to exactly predict their absolute future positions [4]}, i.e., gaze tracking.
So rather than the exact position, this work is the first work to predict the volume of all possible positions.
This is also different from saliency research [5]} because of the need for immediate predictions rather than an analyzable overview result.
Finally, it is also different from eye-head coordination [6]} since such techniques derive the eye gaze from the head movement.
